Justin Bieber could face up to 18 months in prison after being charged with attacking a limo driver.

The pop brat , 19, was accused of hitting him on the head and leaving before police arrived. The driver, who has since quit his job, was taking Bieber and five pals from a nightclub to a hotel.

A police statement said: “An altercation occurred between one of the passengers and the driver. A man struck the driver on the back of the head several times. The driver exited the vehicle and called police. The man who struck him left the scene.”

Canadian Bieber handed himself in to police on Wednesday in Toronto, Ontario, and was charged with assault over the alleged December 30 attack in the city.

He faces court on March 10.

In Ontario a first time assault conviction can typically mean up to 18 months’ jail or a fine. But his lawyer Howard Weitzman said the star was innocent.

Bieber’s manager Scooter Braun tweeted: “I ask people to be kind and hope for the best in people. Not assume the worst.”
